It should be noted that, as mixing device, the LoedigeMixer etc. that MATSUBOCorporation manufactures can be used.
About the method for the mixing of each material during manufacture fast hard material of cement, whole materials can be put into after in mixing machine and carry out high speed shear; Also while continue high speed shear, above-mentioned materials can be dropped in order.The ordering in launching of these materials is not limited, but the calcium aluminate that preferred input ball mill at first etc. are pulverized in advance, then continue high speed shear, while drop into other materials.
Undertaken mixing by high speed shear mode and product in the mixing machine that obtains can directly use as the fast hard material of cement.
The fines content of the fast hard material of cement obtained mixing in high speed shear mode is not particularly limited, but is usually preferably 3000 ~ 9000cm in Blain specific surface
2/ g, is more preferably 4000 ~ 8000cm
2/ g.Lower than 3000cm
2during/g, the manifesting property of initial strength becomes insufficient sometimes, if higher than 9000cm
2/ g, then be sometimes difficult to guarantee mobility, can the activity duration.It should be noted that, 20 minutes ~ 60 minutes can be preferably after water filling the activity duration, to be more preferably 25 minutes ~ 50 minutes.In addition, initial strength have passed through after charging 3 little be constantly preferably 10N/mm
2above, 12N/mm is more preferably
2above.
The compounding amount of the fast hard material of cement of the present invention, according to concrete compounding and change, so there is no be particularly limited to, but usually in the cement composition 100 parts comprising cement and the fast hard material of cement, is preferably 5 ~ 50 parts, be more preferably 10 ~ 40 parts.During lower than 5 parts, sometimes cannot obtain sufficient fast rigid energy, if use higher than 50 parts, then sometimes can reduce in the occasion intensity of long-term maintenance.
As the cement used in cement composition of the present invention, common, the early various portland cement such as strong, super hardening, low-heat, middle heat can be listed, the various mixed cements of blast-furnace slag (slag), flyash (flyash), silicon-dioxide are mixed with in these cement, and be mixed with the filler cement of limestone powder, and with city garbage burning ash, sewage sludge burning ash for raw material and the portland cements such as the environmentally friendly cement (environment protecting cement) that manufactures, can use wherein one or more.Wherein, early strong portland cement is preferably selected.
Concrete containing the fast hard material of cement of the present invention, except sand, sandstone etc., can also combinationally use clay mineral, zeolite plasma permutoid and the inorganic based material such as siliceous micro mist, calcium carbonate, calcium hydroxide, Calucium Silicate powder and the fibrous material such as vinylon fiber, acrylic fibre, carbon fiber as organic system material such as water reducer, high-performance water reducing agent, AE water reducer, high performance AF dehumidifying agent, flowing agent, defoamer, thickening material, rust-preventive agent, frostproofer, economization agent, macromolecule emulsion, condensation conditioning agent etc., wilkinite.
